OIL-CUP.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed May 27, 1914. Serial No. 841,194.

1' 0 all whom it may concern:

Be it known that I, ARTHUR HIRSH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Oil-Cups, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

' The purpose of this invention is to provide an improved oil cup of the characterwhich is adapted to hold oil by means of an absorbent material saturated therewith and compressible to discharge the oil to the bearing to which the cup is attached.

It consists in the elements and features of constructionshown and described, as indicated in the claims.

In the drawings: Figure 1 is a side eleva tion of an oil cup embodying this invention. Fig. 2 is a side elevation showing the parts of the device separated. Fig. 3 is an axial section of the cup body and cap or cover separated. 'Fig. 4 is an axial section of a modified form of cap.

The oil cup shown in the drawings is designed to be made of steel stampings and comprises two principal members telescoped with each other. The outer or cover member, 1, is in the form of a cylindrical cap having formed in its cylindrical wall an exteriorly-protruding spiral bead, 2, forming interiorly a spiral groove, 2, which in its entire course extends once or more around the cap, and which has at intervals in its spiral course a multiplicity of small recesses, 3, leading off from it at the side toward the open end of the cap. The cap member, 1, telescopes over the cup member, 4, constituting a closure or exterior cover for the same and the means of compressing the oil-saturated material with which the cup may be occupied. This cup member, 4, has projecting from one side a slight boss, 4, struck out from the wall of said member adapted to engage and follow the spiral groove, 2, of the member, 1, and to be entered in any one of the recesses, 3, distributed along the course of said spiral groove, by slight longitudinal withdrawal of the cap or closure member, 1, from the cup, 4.

5 is a spring coiled within the cup reacting between the two members to extend them relatively and so to cause the projection, 4, to engage the recesses, 3.

It will be understood that the cavity inclosed by the cup and its closure is designed to be filled with oil-saturated waste which will be compressed for squeezing the oil out of it in the bearings by the telescoping more or less of two members, 1 and 4, and by the pressure of the spring, 5, when such spring is present; and it will also be understood that the reaction of the oil-saturated waste will alone serve the purpose of extending the device to engage the projection, 4, with the recesses, 3, if the spring is omitted. It will be seen that the spiral groove operates after the usual manner of a thread for drawing the two members together when they are relatively rotated in one direction, and extending them when they are relatively rotated in the opposite direction, and that the engagement of the projection, 4, in a recess,

3, looks the members against accidental rot-ation to change their relative extension or telescoped relation.

Fig. 4 shows a modification in which in the outer member, instead of the spirallyextending groove, there is a zigzag groove, 6, in the interior wall, forming an exterior zig-zag rib, 6, thereon. In this form the two members will be closed together by direct axial pressure upon the closure member, accompanied with a back-and-forth rotary movement through asmall angle corresponding to the amplitude of the zigzag groove. The pitch of the several elements of the zigzag groove is preferably not so steep but that the engagement of the pro jection, 4, of the interior member in the angles of the zig-zag will prevent the pressure within the cup from extending the device, but for greater security in this respect there is preferably formed at each angle,- preferably at the side of the zigzag groove toward the open end, a recess, 7, which will receive the projection, 4, and securely hold the closure against any tendency to move outward under the internal pressure due to compressing the packing or due to the spring, 5.

I claim 1. An oil cup comprising a cup member and a closure therefor, adapted to telescope with each other, one of said members having in the face of the cylindrical wall toward the other member a spiral groove with recesses at intervals along its spiral course opening at the side toward the open end of said member, the other member having a projection engaging the spiral groove, and

adapted to be engaged with the recesses by relative movement of the two members tending to extend them.

2. An oil cup comprising a cup member and a closure therefor, adapted to telescope with each other, the exterior member having interiorly a spiral groove with recesses at intervals in its spiral course openingtherefrom at the side toward the open end of said member, the interior member having an outwardly-extending projection which engages the spiral groove and is adapted to be engaged with the recesses by relative movement of said members for extending the in its spiral course, opening therefrom at the side toward the open end of said member, the other member having a pro ection adapted to engage said groove and to be entered in said recesses byfrelativ e movement of said members for extending the device, and a spring inclosed in said cup, reacting between the two members for causing such extension.

4. An oil cup comprising a cup member and a closure therefor, adapted to telescope with each other, one of said members having in the cylindrical wall facing the other member a groove which is inclined with respect to a plane transverse to the axis of the telescoped members and which comprises at intervals along its course recesses for engaging a projection, the other member having a projection adapted to engage said groove and said recesses.
